Introduction: In implant therapy of the edentulous mandible, the decision of implant position is often determined by the need for bone augmentation in the molar region. Bone augmentation requires an extra surgery and thus presents higher risks and costs. In addition, the prosthetic treatment modality of fixed versus removable prosthesis is dependent on implant position. Usually, treatment decision is made in favor of lower costs, less risks and higher patient comfort, which often results in choosing interforaminal implants and removable overdentures. Extra short implants allow for fixed implant supported bridges in the edentulous jaw. Furthermore, in patients with advanced bone loss, pre-treatment with complex bone augmentation is not necessary.
Material & methods: This report describes the treatment protocol for a fixed implant-supported prosthesis in the edentulous mandible based on a patient case. Implant therapy was performed without bone augmentation procedures, and instead 4 mm short implants were inserted in the molar and 10 mm long implants were inserted in the canine region with diameters of 4.1 mm. After implant exposure in a second-stage surgery, a fixed prosthesis with CAD/CAM-fabricated framework and full porcelain veneer was cemented on individualized titanium abutments.
Results: The described treatment with a fixed prosthesis supported by extra short implants in the molar, and regular long implants in the canine region resulted in full rehabilitation of masticatory function in the edentulous jaw. From the patient's perspective the achieved rehabilitation is comparable to a status with own teeth and leads to an improvement in quality of life.
Conclusion: A straight forward implant placement without prior bone augmentation reduces the overall treatment time. In addition, more patients with advanced bone loss in the molar region of the lower jaw may benefit from the presented treatment protocol. From the perspective of the patient treated, the major improvement of chewing ability and the fixed character of the prosthesis made an immense positive impact.

Introduction: In 1926 Wilhelm Herrenknecht succeeded Otto Walkhoff as president of the CVDZ (today: DGZMK). His fame, however, remained well below that of his predecessor. Accordingly, today's knowledge of Herren-knecht's professional work is limited. His relationship to National Socialism has also hardly been discussed. The present contribution takes these gaps in research as an opportunity to provide a synoptic reconstruction of Herren-knecht's life and work, with special emphasis on his role in the "Third Reich".
Material and methods: The study is based on archival records from Berlin and Freiburg i. Br., Herrenknecht's published œ uvre and the memoirs of his assistant Erwin Neu. In addition, a comprehensive evaluation of secondary literature on the history of the Freiburg dental clinic and on Herrenknecht himself was carried out.
Results: Herrenknecht was a practically versed university teacher and specialist politician who strove for balance but left hardly any traces in scientific terms. However, the permanent establishment of the Freiburg Dental Institute can be attributed to him.
During the "Third Reich" Herren-knecht became a member of the NSDAP. According to sources, he was consistently loyal to the regime.
Discussion and conclusion: Herrenknecht's CVDZ presidency (1926–1928) can be classified as a prototypical interim presidency between the "Walkhoff era" (1906–1926) and the "Euler era" (1928–1954). He did not reach the importance of the two colleagues, neither in terms of professional policy nor in scientific terms.
During the Nazi era, Herrenknecht acted as a typical follower. Because of his loyalty to the line, he contributed to the acceptance of the Nazi regime – albeit without appearing as a fervent National Socialist.
